Step-by-step explanation:

There are 10 data points so the points 5 and 6 is the median multiply by 2 so 62+68=130 130/2=65

Answer:

y = x - 2

Step-by-step explanation:

The equation of a line can be known as y = mx + b, with m being the slope and b being the y intercept.

1. Find the Slope

The slope can be known as the change in y/change in x.

Two points: (2,0), (0,-2)

-2 - 0/ 0 - 2 = -2/-2 = 1

Slope is 1

So now we can replace the m as 1. So that is y = x + b

2. Find the y intercept

The y intercept is -2 because that is the point where the line meets the y axis.

So our equation is y = x-2

How far from the base of the house do you need to place an 18’ ladder so that it exactly reaches the top of a 14’ wall?

Anastaziya [24]

Answer:

Length of Ladder(Hypotenuse)=18

Height of wall(Opposite) =14

How far from the base... This talks about the adjacent or distance between the wall and the base.

You can get your answer from Pythagoras theorem

Which states

The square of the hypotenuse is = to the squares of the adjacent and Opposite sides

H² = O² + A²

We're looking for the adjacent "A"

Making A the subject

A² = H² - O²

A= √H² - O²

A= √18² - 14²

A=√128

A= 8√2'

A leprechaun places a magic penny under a girls pillow. The next night there are 2 magic pennies under her pillow. The following

kiruha [24]

Answer:

After 47 days she will have more than 90 trillion pennies.

Step-by-step explanation:

At the beginning there was 1 penny. At the second day the amount of pennies under the pillow became 2.

The amount of pennies doubled each day. So the series is,

$1,2,4,8,16,32,.....$

This series is in geometric progression.

As the pennies from each of the previous days are not being stored away until more pennies magically appear so the sum of series will be,

$S_n=\dfrac{a(r^n-1)}{r-1}$

where,

a = initial term = 1,

r = common ratio = 2,

As we have find the number of days that would elapse before she has a total of more than 90 trillion, so

$\Rightarrow 90\times 10^{12}\le \dfrac{1(2^n-1)}{2-1}$

$\Rightarrow 90\times 10^{12}\le \dfrac{2^n-1}{1}$

$\Rightarrow 90\times 10^{12}\le 2^n-1$

$\Rightarrow 2^n\ge 90\times 10^{12}+1$

$\Rightarrow \log 2^n\ge \log (90\times 10^{12}+1)$

$\Rightarrow n\times \log 2\ge \log (90\times 10^{12}+1)$

$\Rightarrow n \ge \dfrac{\log (90\times 10^{12}+1)}{\log 2}$

$\Rightarrow n \ge 46.4$

$\Rightarrow n\approx 47$

Find two consecutive whole numbers that 19 lies between

sertanlavr [38]

Answer:

I don't believe that this is possible unless the answer you are looking for is 18, 20.

Step-by-step explanation:

The meaning of cosecutive whole numbers is a whole number followed directly after another. 14, 16, 18 are not consecutive though they are each spaced from each other by 2.

Answere and How to do

Angelina_Jolie [31]

Answer:

-25

Step-by-step explanation:

if you are multiplying x by -2/5 you have to divide each side by it to get

x = 10 ÷ -2/5

and if you change it to (10/1)/(-2/5)

=(10/1) • -5/2

and whene you multiply them you get -50/2

which is -25/1 or -25
